3 Claims.

This invention relates to ice shaving machines. It is an object of this invention to provide an ice shaving machine easily assembled and and repair.

which can be quickly and disassembled for cleaning It is the further object of this invention to provide an ice shaving machine which is particularly adapted to form ice s the type produced in It is the further obj havings out of ice cubes of electrical refrigerators. ect of this invention to provide an ice shaving machine embodying means for the formation of shaved ice masses.

It isa further object of this invention to provide an ice shaving machine asset forth in the preceding object in w may be formed on a s in use.

hich took the shaved ice masses or bar for convenience It is a further object of this invention to provide an ice shaving machine as set forth in the preceding two objects in which the shaved ice masses may be flavored to form confections.

Other objects and attendant advantages will appear in the following description of one practical embodiment the accompanying dra of my invention illustrated in wing, in which:

Fig. l is a view partly in section of an ice shaving machine, the portion in section being taken illustrated in Fig. 1.

Fig. 3 is a detail view of a rotating member of the machine.

Fig. 4 is a section taken on line 4-4 of Fig. 3. Fig. 5 is a fragmentary elevation of the machine.

Fig. 6 is a side View of an end cover for the machine.

Fig. 7 is an elevati shaved ice mass of the type onal view of a compressed which may be formed within the machine, the View showing the mass as being formed on a stick.

The machine illustrated in the drawing comprises a housing It constructed with a through which the machine is secured in place upon a table or other suitable support.

sageway I5 slightly 1a rger in cross-sectional area than ice cubes of the type referred to. Such passageway is formed at an angle to the axis of the machine in order that blades of the cutting apparatus later described will engage with corners of the ice cubes rather than the sides. the object 5 being to reduce the shock of engagement, and to obtain a shaving movement.

A cover It is provided for the upper end of the extension l4, and slidably mounted in such cover there is a plunger I? for applying downward pres- 10 sure to the ice within the extension i i. The plunger I! comprises a rod is which extends through an aperture formed in the cover IS, a plate 19 mounted at the lower end of the rod is and designed for engagement with the ice. and l5 a head 28 secured to the upper end of the rod 18.

Rotatably mounted within the housing I 0. there is a hollow member 2|. Such member is supported at its forward end by a cylindrical extension 22 which extends through an aperture 2320 in the forward wall of the housing, and at its rear end by a plurality of spaced lugs 2 which engage with a flange 25 on the rear end of the housing. It is formed With a central horizontal recess 26 which tapers outwardly towards the 25 rear of the housing, and is constructed with four exterior flat surfaces 21 which extend between the lugs 24, and with four slots 28 located below the passage l5 in the extension i4. and arranged at the forward edges of the surfaces 27.

Secured upon the fiat surfaces 2'! by means of screws 29, there are four plates 30 formed with cutting edges 3| which extend over the slots 28. These plates are formed with slots 32 for reception of the screws 29, instead of with aper- 35 tures, in order to facilitate their removal and replacement.

The extension 22 on the member 2| protrudes beyond the forward end of the housing ill, the protruding portion 33 being reduced and thread- 40 ed. Screwed onto the threaded portion 33 in a manner to engage with a shoulder 34 at the rear as a means for maintaining the member 2| in position.

The extension 22, in addition to being formed with screwed onto the outer end of the rod 38 through which force is applied to the plunger. A spring 42 mounted on the rod 39, intermediate the end of the extension 22 and the head 4|, serves to normally maintain the plunger 38 in the position shown.

A plate 43 is provided for closing the rear end of the member 2|. Such plate is formed with hooks 44, which, when the plate is secured in place, are inserted between the lugs 24 and turned to overlap such parts. Such plate is further formed with a lug 45 on its rear surface to facilitate turning, and with an aperture 46 which extends through the center of the lug 45. The purpose of the aperture 46 is to permit the insertion into member 2| of a stick or bar as hereafter explained.

The machine described is capable of being used either to produce loose shavings or to produce compact masses of shavings. To produce loose ice shavings, the cover 43 is removed and ice, preferably in the form of cubes of the type referred to, inserted within the: extension l4. Ice in other shapes may, of course, be used, but the eiiiciency of the machine will be decreased due to a reduction in the size of the shavings. After the insertion of ice within the extension l4, the crank 35 is turned in a direction to produce clockwise rotation of the member 2| as viewed in Fig. 4, pressure at the same time being applied to the ice by means of the plunger l1. As the blades 30 are moved across the opening at the lower end of the extension M by the rotation of the member 2|, they will operate to out shavings from the ice. The shavings thus produced will drop into the interior of the member 2| and then slide downward on tapered inner surface of such member to the rear end of the housing where they can be caught in a suitable container.

To produce compressed ice masses, as previously mentioned, the cover 43 is secured in place upon the rear end of the member 2| and the machine operated in the manner just described. In such case, the shavings entering the member 2| collect against the cover 43, and when a sufficient amount of shavings has collected, the amount being determined from downward movement of the plunger H, the plunger 38 is moved inward compressing the shavings against the cover to form a frusto-conical mass 41 as illustrated in Fig. 7. If desired, a stick or bar 48, to

serve as a handle, may be inserted through the aperture 46 and the shavings compressed upon such part. In addition, the ice masses may be flavored to form confections, or the liquid in the ice flavored before being frozen to attain the same result. Removal of the ice masses after formation is effected by detaching the cover 43 as will be readily understood.

The machine is disassembled by first unscrewing and removing the head 4| from the rod 39. The crank 35 is then unscrewed and removed from the extension 22, after which the member 2| and the plunger 38 can be withdrawn from the housing l0, and plunger 38 removed from the member 2|.

What I claim as new is:

1. In an ice shaving machine, a casing, a rotatably mounted hollow member in said casing, said member being formed with an open end and with a slot in its side wall, cutting means on the exterior of said member overlapping the aforesaid slot, a hollow extension on said casing designed to receive ice and communicating with the interior of said casing adjacent said cutting means, a. plunger in said extension for holding the ice in such part in engagement with said member, means for rotating said member to cut shavings from the ice, a removable cover for the aforesaid open end of said member formed with an aperture for insertion of a handle, and a plunger in the opposite end of said member arranged for movement in the direction of the aforesaid open end of said member to compress the shavings cut by said cutting means into a solid mass.

2. In an ice shaving machine, a housing, a hollow shaving cylinder rotatable therein, shaver blades thereon so that the shavings of ice will be deposited in said cylinder, a cap to be attached to said cylinder to confine the shavings, an opening through said cap to receive a handle member, and a plunger in said cylinder to compress the shavings about said handle.

3. An ice shaver including a housing, a rotatable drum therein, a shaver blade thereon, a rectangular opening in said housing for the insertion of ice cubes to be shaved, said opening being disposed so that the cube therein will be first contacted at a corner by said blade to obtain a shaving action.
